Landscape dominated by depressions, pits, and caves that is created by the thawing of ground ice in high latitude locations. Resembles karst landscape but is not created by chemical weathering.

high-altitude landscape holed pitted by selective permafrost thawing. Karst without the chemical weathering..

in periglacial areas, the melting of ground ice causes subsidence and creates a very uneven surface.

The process by which characteristic landforms result from the thawing of ice-rich permafrost or the melting of massive ground ice.

Land surface in Arctic areas characterised by very irregular surfaces of marshy hollows and small mounds formed when ice-rich permafrost thaws.

(geology) A region similar in appearance to karst topography, characterized by an irregular land surface, with bogs, pits, and other depressions, formed in areas of permafrost due to ice melting.
